some rmx inn'rm, or Games 'rown, WEST mam anon-sore To all whom it may concern:

Be it known that '1, JOHN F. MARTIN, a citizen of the United States, residing at Charles Town, in the county of Jefferson and State of West Virginia, have invented certain new and useful I n' roveinents in Shoe-Soles; and I do hereby eclare the following to be a full, clear, and exact description of the invention, such as will enable Others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in shoe soles and has for'one of its objects the provision of a device of this character which will relieve the pressure upon the ball of the foot and toes, thereby obviating calli and coins caused thereby.

Another object of this invention is the provision of means for supporting the arch of the shoe, thereby obviating falling arches to feet and which willstrengthen falling arches when used thereon.

"A further object of this invention is the provision of a shoe sole of the above stated character, which shall be sim le, durable and efiicient, and which may manufactured and sold at a comparatively low cost.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following descrition and accompanying drawing, in which:-

igure 1 is a'bottom plan view of a shoe sole constructed in accordance with my invention,

' Fig. 2 is a longitudinal sectional view of the same, illustratin the inclination ofthe arch support and ta en on line 2-2 of Fig.

the sole taken on line 3-3 of Fig. 1, looking in the direction indicated by the arrows.

Fig. 4 is an end view of the heel portion a of the sole.

Referring in detail to the drawing, the

numeral 1 indicates as an entirety, a shoe sole wh1ch is preferably constructed from a su table composition of material and conslsts of a ball portion 2, instep portion 3, and a heel portion 4. The ball portion 2 of the shoe sole has formed upon its outer face a raised portion 5 which is concaved -as clearly illustrated in Figs. 2 and 3 to form a recess 6 upon the outer face of the shoe sole for the purpose of forming a cushion' for the ball and toes of a foot. The raised portlon 5 is spaced from the edges of the sole for the purpose of providing a space 7 to which the shoe upper may be secured in the ordinary manner by stitches and which will prevent the stitching from coming in' contact with the ground thereby obviating wear thereof. The recess or depression 6 will permit flexing or sag ing of the sole at such a point when wa ing or standing thereon, thereby formin a cushion tothe ball and toes'of the foot w ich prevents calli, toms and bunions. A raised extension 8 is formed, upon the raised portion 5 and extends rearwardly under t e inste portion 3 terminating t e ,an abrupt shoul er 9 at the beginning 0 heel portion 4 and is adapted to contact with the -ordinary heel of' a shoe (not 'shown'); The outer or upper face of the raised portion 8 is inclined downwardly from the abrupt shoulder 9' until it communicates in a plane with thebottom wall of the recess 6* for the purpose of conforming to the contour of .the outer face of the sole. When the foot is positioned upon the sole, permitting the tion 4, the arch of the sole will be supported by the raised extension 8 obviating allmg arches and which will support falling arches when applied thereto.

While I have shown and described the preferred embodiment (if my invention, it

eelto rest upon the heel pot-- will be understood that minor changes in construction, combination and arrangement of parts mayv be made without departing from the spirit and scope of the invention 5 as claimed. i

Having thus described my invention, what I claim is As a new article of manufacture, a shoe sole having a depression adapted to permit- 10 flexing, of the sole when under weight, a

V, p raised portion surrounding said depression,

and .a projection formed on the raised porhon'to support the arch portion of the sole of the shoe and inclined downwardly and.

terminating in a plane with the depression.

In testimony whereof I afiix my signature in presence of two witnesses.
